A few weeks ago a windows update broke my registry bad. So bad I had to do a restore. Appearently I had a BSOD during the update. But I didn't notice it as I had let the computer shut down when I went to bed. Next morning the computer was turned on with a fatal error recovery message on screen. After that my PMDG licenses all stopped working. The solution was a system restore from a point before the update. I don't believe malware was a part of my problem.

Vernon, glad you got it sorted. Viruses and malware have a nasty habit of getting into your registry and creating havoc with a whole shed load of things. When things start to happen on your computer with no rational explanation, quite often you can pin it down to a virus or malware. But as Craig said, it has nothing to do with PMDG whatsoever, it could just as easily have been some other addon or addons you were experiencing difficulties with. Do yourself a favour though, if you haven't already done so, get yourself a  good quality backup system in place so that in future, if need be, you can simply reinstall Windows and FSX simply and easily!

Yep thanks for that i'll keep on scanning

 

Going to get myself a external hard drive and back it up using acronis

A very wise move Vernon. Acronis has got me out of many a scrape over the years. Having that assurance is very comforting.

Do you have to buy an external HDD for acronis?

As long  its the same size of the hard drives you have installed, so be best if  its an external hard drive,  thats what I got anyways

Got an SSD and HDD, will purchase one tonight and back it up with acronis
